If you are left always scratching your head thinking of a birthday present, you could always look to Norway for inspiration as its government is considering gifting a mountain to Finland to mark the country's 100 years of independence from Russia.
The unusual gesture was the brainchild of retired Norwegian Mapping Authority employee Bjørn Geirr Harsson.
By moving the border by just 40 metres, Halti would find itself in a different country. Halti stands at 1,365m above sea level - around the same height as Ben Nevis.
Given Norway has over 300 mountain peaks at over 2,000 metres above sea level, it's thought the gift would make a big difference to Finland and would its highest mountain.
The highest point in Finland is among the mountain range known as Halditsohkka.
Halditsohkka is only around 40 metres shorter than the nearby Halti.
